[XeTeX] Sub-optimal diagnostic from XeTeX/xdvipdfmx when including non-existent page from PDF

[Philip Taylor]

Given the following input, XeTeX/xdvipdfmx reports :

This is XeTeX, Version 3.141592653-2.6-0.999993 (TeX Live 2021/W32TeX) (preloaded format=xetex)

restricted \write18 enabled.

entering extended mode

(./Hoi-An vegan menu (combine pages, bg).tex [1]

xdvipdfmx:fatal: Image inclusion failed for "./Hoi-An vegan menu (separate pages).pdf".


No output PDF file written.

)

Error 1 (driver return code) generating output;

file Hoi-An vegan menu (combine pages, bg).pdf may not be valid.

SyncTeX written on Hoi-An vegan menu (combine pages, bg).synctex.gz.


Transcript written on Hoi-An vegan menu (combine pages, bg).log.


for source :

\def \source {"Hoi-An vegan menu (separate pages).pdf" }


\setbox 1 = \vbox {\XeTeXpdffile \source page 1 width \dimexpr \hsize / 4 - \tuckloss - 0,666 \rulewidth \relax}\relax

\setbox 2 = \vbox {\XeTeXpdffile \source page 2 width \dimexpr \hsize / 4 - 0,666 \rulewidth \relax}\relax

\setbox 3 = \vbox {\XeTeXpdffile \source page 3 width \dimexpr \hsize / 4 - 0,666 \rulewidth \relax}\relax

\setbox 4 = \vbox {\XeTeXpdffile \source page 4 width \dimexpr \hsize / 4 - \tuckloss \relax}\relax

If the final line of the immediately preceding is commented out, the document compiles with success.  It is therefore clear that the problem lies not with "./Hoi-An vegan menu (separate pages).pdf" per se, but rather with the assumption that "./Hoi-An vegan menu (separate pages).pdf" contains four or more pages.  It would therefore be very helpful if XeTeX/xdvipdfmx could report that the problem occurred when trying to access page 4, rather than merely stating that « Image inclusion failed for "./Hoi-An vegan menu (separate pages).pdf" ».
